| Explanation & Hint:
To locate where the issue is in the network when a web page is taking longer than normal to load, a technician should use:
- tracert (or traceroute on Unix/Linux systems): This tool traces the path that a packet takes to reach a destination and displays the time it takes to hop from one router to another. It can help identify at which point in the path there might be delays or a bottleneck causing the increased load time.
While the other tools listed are useful for different purposes, they wouldn’t be as effective in locating the issue in the network path:
- ipconfig /displaydns: Displays the contents of the DNS client resolver cache, which includes the DNS records recently queried by the computer. This command is useful for checking cached DNS records but doesn’t help to locate network delays.
- nslookup: This is a network administration command-line tool used for querying the Domain Name System (DNS) to obtain domain name or IP address mapping or for any other specific DNS records. It’s useful for checking if DNS resolution is part of the problem but doesn’t show the network path or where delays occur.
- ping: A ping command would tell you if the destination is reachable and what the round-trip time (RTT) for the message is, but it won’t show where along the path potential issues are occurring.
Using tracert, the technician can see each hop along the path to the destination web server and the time taken to reach each hop, which can help locate the segment of the network that is causing the delay. |
